At a Wednesday afternoon press conference, the Sheriff's Office corrected itself after initially stating the boy was 2-years-old.

Erika Wigstrom, 20, has been arrested and charged on one count of first-degree murder.

Lucas Ruiz was poisoned Jan. 24, and he died later that day, according to the Sheriff's Office. The Sheriff's Office initially told WDSU the child died Jan. 29.

After an autopsy, it was determined the child had a blood alcohol content of .280 at the time of his death.

In October 2012 when the child was 2 months old and in Ochsner Hospital awaiting open heart surgery, it was found he had a blood alcohol content of .289, the Sheriff's Office says.

His father, 19-year-old Cesar Ruiz, admitted to pouring the alcohol directly into the victim's feeding tube, according to the Sheriff's Office. He was arrested following the admission on charges of attempted first-degree murder and second-degree cruelty to a juvenile, the Sheriff's Office says.

However recently, Wigstrom told detectives that Cesar Ruiz was not the person that poisoned Lucas Ruiz during the initial incident and that she in fact was the person who injected and poisoned him. Wigstrom informed investigators that she injected alcohol into Lucas’ feeding tube on both occasions because she didn’t want Lucas Ruiz to suffer any longer.

The case against Cesar Ruiz remains pending in the Jefferson Parish 24th Judicial District Court.
